1 Claim. (Cl. 242-106) This invention relates to improvements inshipboard aerials, and it is the object of the invention to provide aship-board aerial system which will greatly simplify the work ofelevating, hoisting or lowering aerials on shipboard.

The operation of elevating or lowering a shipboard aerial is anextremely difficult one, particularly when adverse weather conditionsare encountered.

The present invention is designed to reduce the amount of exertionrequired for such operations to a minimum of the effort heretoforerequired, and to further provide for a construction which is relativelysturdy, durable and positive in operation.

The structure of this invention allows the user to attain completecontrol of the aerial during the hoisting and lowering thereof, andprovides for automatically locking the same at any selected position.

These and other advantageous objects, which will appear from thedrawings and from the description hereinafter, are accomplished by thestructure of my invention, of which an embodiment is illustrated in thedrawings. It will be apparent, from a consideration of said drawings andthe following description, that the invention may be embodied in otherforms suggested thereby, and such other forms as come within the scopeof the appended claim are to be considered within the scope and purviewof the instant invention.

In the drawings:

Fig. 1 is a fragmentary elevational view of a shipboard aerial systemembodying the invention,

Fig. 2 is an enlarged fragmentary horizontal sectional view, taken online 22 of Fig. 1,

Fig. 3 is a vertical elevational view, taken on line 33 of Fig. 2,

Fig. 4 is a perspective View of a bracket unit and associated partsembodying the invention, and

Fig. 5 is an enlarged, fragmentary, elevational view of a means forsecuring the ends of the lines pursuant to the invention.

As shown in the drawings, the shipboard aerial system of this inventionis adapted for use in connection with two spaced vertical masts 10, 11,on shipboard 12. A pair of open brackets 13, 13 is secured to said mastsand directed toward each other. The parts associated with the mast 11are, pursuant to the invention, preferably duplicate parts of thoseshown in connection with the mast 10. Therefore, the followingdescription of one will sufiice for both. A drum 13 may be secured tothe mast 10, as, for example, by welding the same thereto, as noted at14 (Fig. 2), or in any other manner. Drum 15 is rotatably mounted in thebracket 13 as shown at 16. A handle member 17 is keyed to the axis ofthe drum, preferably, as shown in Figs. 3 and 4, by providing a rod 18fixed to the, axis of the drum and normally disposing the handle 17 wellbeyond said axis and directed away from the drum, to facilitateactuation.

United States Patent The handle 17 is preferably connected to the freeend of rod 18 by hinge means 19. Thus it will be apparent that bydisposing the handle 17 in an outwardly directed position relative tothe drum, as shown in Fig. 4, the drum may be conveniently rotated,while, by pivoting the handle 17 into a position from its normaloperative position (as shown in dotted lines in Fig. 3), the parts maybe automatically locked. It will be apparent that any tendency to rotatethe drum while the handle is in its inward position (dotted lineposition of Fig. 3) will cause the handle to abut the bracket 13,precluding free rotation of the drum. This is an important safety factorwhich will preclude the movement of the aerial from any position ofadjustment. A pair of pulleys 25, 25 is secured to the masts 1G, 11, atpoints spaced well above the brackets 13, 13', and the aerial 26 issecured at its ends to lines 27, 2'7, entrained over said pulleys 25,25, and over the drums positioned in the brackets 13, 13. A take-up andtensioning means 28, 29 connects the ends of the lines 27, 27.

In initially assembling the shipboard aerial pursuant to the invention,the pulley 25 and bracket 13 are connected to the mast; one end of theline 27 is attached to the turnbuckle 28, passed through the pulley 25at the top of the mast and then down to the drum 15; it is entrainedseveral times circumferentially of the drum, and then the free ends ofthe lines are connected to the spring 29 and turnbuckle 28. Theturnbuckle 28 will permit taking up of any slack of the line from timeto time; entraining of the line around the drum will take up asubstantial amount of any stress or strain present. The aerial may befastened to the line at any points. The leverage attained pursuant tothe structure of this invention in the hoisting or lowering operation issuch that the operator has complete control at all times. The structuremay be made to accommodate any size of line. The term aerial, as usedherein, shall be deemed to include a horizontal line used for thereception of radio or other waves, which must be elevated and loweredperiodically.

While the aerial system herein described is primarily designed forshipboard use, it is adapted to other uses wherein it is secured tospaced vertical members. The terms shipboard aerial and vertical mastson shipboard" and similar terms, as used herein, shall be deemed toinclude such other uses.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

A structure for moving an object vertically comprising an elongated postadapted to be secured at its lower end to a supporting surface, abracket secured to said post adjacent the lower end of the post, saidbracket comprising a pair of spaced, parallel leg members secured at oneend to the post and extending therefrom at right angles to thelongitudinal axis of the post, a shaft rotatably journalled in the legmembers, a drum keyed to said shaft and disposed intermediate the legmembers so that an object may be secured to a line entrained over thebracket drum and thereby moved vertically, said drum being of greaterdiameter than the width of the leg members so as to be mediallyintersected thereby, said shaft having an end extended through one ofsaid leg members, a first rod keyed at one end to the extended end ofthe shaft of substantially greater length than the diameter of the drum,for rotation in a plane at right angles to the longitudinal axis of thedrum shaft, a second rod, a handle secured to the second rod, meanspivotally connecting the second rod to the other end of said first rodon an axis disposed at right angles to and spaced from the longitudinalaxis of. said drum shaft, so that said handle may be positioned toextend from the rod outwardly of the bracket and drum to rotate the ice3 drum, or for selective rotation to a position inwardly of the bracketand drum so that on rotation of the drum, and, thereby, the first andsecond rods with the handle in the last mentioned position, said handlewill be rotated against the post precluding further rotation of thedrum. 5
